Matt for Model Number gsd4030y72ww; serial number vr768977b The power tower broke off the spray arm. Your site is very well-designed and when I look at the schematic it appears that the spray arm has been redesigned and it no longer has the counter-rotating "wings' at either end of the arm. Please confirm. Additionally, although I am extremely mechanical I cannot figure out how to get the old spray arm off the "hub" or whatever it is called. So, I need to know which part or parts to order including any replacement screws, connectors, etc. and then how to get the old assembly off. Thank you for your assistance it is truly appreciated.
Answer Hello Matt. You will insert a screwdriver into the slot under the spary arm WD22X155 and unscrew it off the assembly. Read More... Answered by AppliancePartsPros.com | Wednesday, August 29, 2012
